The rapid development of the polyurethane industry drives the growth of market demand for polyurethane catalysts

Catalyst refers to a substance that can increase the reaction rate without changing the total standard Gibbs free energy change of the reaction. Polyurethane catalyst is an additive containing organic amines and organic metal salts that can accelerate the polyurethane reaction. Polyurethane catalysts are mainly divided into two categories: organometallic compounds and tertiary amine catalysts. Commonly used varieties include triazine trimerization catalysts (DY-41), dimethylcyclohexylamine (DY-8) and bisdimethylaminoethyl Ether (DY-1) etc.

There are many methods for preparing polyurethane catalysts, including liquid phase catalytic hydrogenation, fatty acid method, alcohol method, etc. At present, the production of polyurethane catalysts is difficult and the production process is complicated. Various parameters such as the amount of raw materials, temperature, and pressure need to be strictly controlled. The liquid phase catalytic hydrogenation method can be used to prepare high-quality polyurethane catalysts and is expected to become its mainstream in the future. Preparation.

There are many types of polyurethane catalysts, and tertiary amine catalysts are their representative products. Tertiary amine catalysts have the advantages of good stability and high reaction selectivity. They can be used to make polyurethane foam and can increase the softness of the foam. In recent years, Chinese enterprises and scientific research institutions have continued to increase their research efforts on tertiary amine catalysts, which will further accelerate the development of the polyurethane catalyst industry.

According to the “2023-2028 China Polyurethane Catalyst Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, polyurethane Catalysts are mainly used for the synthesis of polyurethane (PU). Polyurethane, also known as polyurethane, is a polymer compound that can be used to produce elastomers, foam plastics, fiber plastics, fibers, resins, coatings, adhesives and other products. It is widely used in building materials, home appliances, automobiles and other fields. my country is the world’s largest producer and consumer of polyurethane. In 2022, my country’s polyurethane output will reach 15.125 million tons, accounting for nearly 50% of the world’s total output. With the rapid development of downstream industries, my country’s polyurethane catalyst market demand is increasingly strong.

The main manufacturers of polyurethane catalysts in my country include Yunnan Tin Industry Co., Ltd., Jiangsu Meside Chemical Co., Ltd., Wanhua Chemical Group Co., Ltd., Yangzhou Chenhua New Materials Co., Ltd., Zhejiang Wansheng Co., Ltd., Huamao Weiye Green Technology Co., Ltd., etc. Wanshengwei, a subsidiary of Wansheng Co., Ltd., focuses on the research and development, production and sales of polyurethane catalysts and special fatty amine products. Currently, the company’s polyurethane catalyst output ranks first in the world.

Industry analysts said that polyurethane has excellent performance and is widely used in many fields. As an important auxiliary for the preparation of polyurethane, polyurethane catalysts are in great demand in the market. increasingly prosperous. Tertiary amine catalysts are representative products of polyurethane catalysts and have the advantages of good stability and high reaction selectivity. It is expected that in the future, as local companies continue to make breakthroughs in production technology, the prosperity of my country’s polyurethane catalyst industry will continue to increase.
